Notes: 1. The converter output voltage shall be stable when (13,200µF total) tantalum low ESR filter capacitors are connected across the output of the converter.
2. For 3.43 Input Voltage Rail having I_Omax = 40A, the minimum input filter capacitor required is 6600µF (use multiple 330µF tantalum capacitor having 60mΩ ESR.)
3. For 5.00 Input Voltage Rail having I_Omax = 55A, the minimum input filter capacitor required is 3960µF (use multiple 330µF tantalum capacitor having 60mΩ ESR.)
